Computer memories: the history of computer form

This paper looks at the computer as a truly global form. The similar beige boxes found in offices across the world are analysed from the perspective of design history rather than that of the history of science and technology. Through the exploration of an archive of computer manufacturer's catalogues and concurrent design texts, this paper examines the changes that have occurred in the production and consumption of the computer in the context of the workplace, from its inception as a room-sized mainframe operated through a console of flashing lights, to the personal computer as a 'universal' form, reproduced by many manufacturers. It shows how the computer in the past has been as diverse as any other product, and asks how and why it now appears as a standardised, sanitised object. In doing so our relationship with the office computer, past and present is explored, revealing a complex history of vicissitude.</p

Indicators for Spatial Planning and Territorial Cohesion: Stakeholder-Driven Selection Approach for Improving Usability at Regional and Local Levels

© 2015 Regional Studies Association.González A., Daly G., Pinch P., Adams N., Valtenbergs V., Burns M. C. and Johannesson H. Indicators for spatial planning and territorial cohesion: stakeholder-driven selection approach for improving usability at regional and local levels, Regional Studies. Reformed European Union Cohesion Policy aims at delivering a coherent investment policy to achieve the Europe 2020 Strategy goals and to reduce regional disparities. Spatial indicators measure progress towards agreed policy goals and support place-based approaches to policy implementation. Despite the range of indicators available, development of a standardized approach in support of Cohesion Policy has received little empirical attention. A set of key spatial indicators has been identified in a stakeholder-driven process. The methodological approach applied is presented and resulting indicators critically appraised with regards to their applicability and potential for assisting improved integration between Cohesion Policy and spatial planning

STS in management education: connecting theory and practice

This paper explores the value of science and technology studies (STS) to management education. The work draws on an ethnographic study of second year management undergraduates studying decision making. The nature and delivery of the decision making module is outlined and the value of STS is demonstrated in terms of both teaching method and module content. Three particular STS contributions are identified and described: the social construction of technological systems; actor network theory; and ontological politics. Affordances and sensibilities are identified for each contribution and a discussion is developed that illustrates how these versions of STS are put to use in management education. It is concluded that STS has a pivotal role to play in critical management (education) and in the process offers opportunities for new forms of managin

Application of Optimal Control to CPMG Refocusing Pulse Design

We apply optimal control theory (OCT) to the design of refocusing pulses suitable for the CPMG sequence that are robust over a wide range of B0 and B1 offsets. We also introduce a model, based on recent progress in the analysis of unitary dynamics in the field of quantum information processing (QIP), that describes the multiple refocusing dynamics of the CPMG sequence as a dephasing Pauli channel. This model provides a compact characterization of the consequences and severity of residual pulse errors. We illustrate the methods by considering a specific example of designing and analyzing broadband OCT refocusing pulses of length 10 t180 that are constrained by the maximum instantaneous pulse power. We show that with this refocusing pulse, the CPMG sequence can refocus over 98% of magnetization for resonance offsets up to 3.2 times the maximum RF amplitude, even in the presence of +/- 10% RF inhomogeneity.Comment: 23 pages, 10 figures; Revised and reformatted version with new title and significant changes to Introduction and Conclusions section
